Open Source C Archiving Software for Mac

Info-ZIP portable compression/archiver utilities (Zip, UnZip, WiZ, etc.)

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections.

Version 1.0.9 contains a fix to "integer overflow" problem. This happens when "one-shot" decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. After the overflow happens, memcpy is invoked with a gigantic num value, that will likely cause the crash. Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in RFC 7932. Brotli is open-sourced under the MIT License. You can download and install brotli using the vcpkg dependency manager.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

Greenstone is a complete digital library creation, management and distribution package created and distributed by the New Zealand Digital Library Project. There are two major versions of the software. Greenstone 3 is under active development, and is recommended for download. We also provide maintenance releases for its forerunner, Greenstone 2. Featured download not what you're looking for? Click "Browse all files" to access binaries and source releases of both versions.

Additional error correction for CD, DVD and BD media.

Rar Expander is a MacOSX program which extracts the files contained in single or multi-volume RAR archives. It uses the official unRAR library internally so it is fully compatible with archives produced by WinRAR.

pngcrush and other tools for manipulating PNG (Portable Network Graphics) and MNG (Multiple-image Network Graphics) files.

Remote Subversion repository dump

Providing a tool to apply the data-recovery capability concepts of RAID-like systems to the posting & recovery of multi-part archives on Usenet.

Moved to GitHub.com/gdraheim/zziplib/ The ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by Zlib. It provides functions that transparently access files being either real files or zipped files, both with the same filepath

ARC is used to create and maintain file archives. An archive is a group of files collected together into one file in such a way that the individual files may be recovered intact. This repo is obsolete. Use github.com/hyc/arc instead.

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

Fpart is a tool that helps you sort file trees and pack them into bags (called "partitions"). It is developped in C and available under the BSD license. It splits a list of directories and file trees into a certain number of partitions, trying to produce partitions with the same size and number of files. It can also produce partitions with a given number of files or a limited size. Once generated, partitions are either printed as file lists to stdout (default) or to files. Those lists can then be used by third party programs. Fpart also includes a live mode, which allows it to crawl very large filesystems and produce partitions in live. Hooks are available to act on those partitions (e.g. immediatly start a transfer using rsync(1)) without having to wait for the filesystem traversal job to be finished. Used this way, fpart can be seen as a powerful data migration tool.

Vchanger may be used with the Bacula Open Source network backup system to emulate a magazine-based tape autoloader using disk partitions on fixed or removable disk drives as virtual magazines and files on those partitions as virtual tape volumes.

The littleutils include duplicate file finders (repeats, repeats.pl, repeats.py), image optimizers (opt-jpg, opt-png, opt-gif, recomp-jpg), file rename tools (lowercase, uppercase, pren), archive recompressors (to-gzip, to-bzip2, to-bzip3, to-7zip, to-lzma, to-lzip, to-xz), a tempfile utility (tempname), file property tools (filedate, filemode, filenode, fileown, filesize, and lrealpath), and others. See the README file for more details.

yydecode is a highly portable decoder for yEnc encoded binaries on Usenet. It offers superior functionality to uudecode, and can be used as a drop-in replacement.

Free virtual appliance to backup and replicate Linux servers and ©VMWare ©ESXi virtual machines from version 5.1 to 8.0. https://33hops.com/xsibackup-app-detailed-installation-instructions.html ©XSIBackup-App connects to multiple Linux or ©ESXi servers and backs VMs & files up to, local disk, NFS, iSCSI, Samba, etc... or to any Linux or ©ESXi server over IP, it just needs the SSH port open. This appliance is based in CentOS 7 and has root access. You can install any available software, including drivers for Amazon S3, Azure, Google Cloud, etc... We have improved speed with regards to the hypervisor service versions, mainly due to more flexible buffering. It follows the same principles and command line arguments as ©XSIBackup-DC. This new approach has many advantages over the software running directly in the Hypervisor OS, as it can backup an unlimited number of servers from a centralized console and you don't need to install anything in the Hypervisor OS

The RLE compression pack is a set of utilities to compress and decompress files using RLE algorithm.

iSFV is an easy to use integrity checker for SFV files. Use it to test for corrupt files in packages that come with SFV files. You can also use it to edit or create your own SFV files.

Basic Compression Library is a portable library of well known compression algorithms, such as Huffman coding, written in standard ANSI C. It is intended to serve as a set of building blocks for specialized compression algorithms.

Clean is a program that searches for backup files and such identified by regular expressions in a ~/.cleanrc, and deletes them: possibly interactively with a per-file y/n decision, or in a batch mode. Clean is written in C and targets Unix/POSIX.

Depack routines for old Atari ST packing programs like Ice, Atomic etc.

UnRarX is a Mac OS X Cocoa application that allows you to expand rar archives on MacOS X.
